Click library

• Author : MikroE Team
• Date : Jan 2020.
• Type : I2C type

Software Support

We provide a library for the AudioAmp Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for AudioAmp Click driver.

Standard key functions :

• Config Object Initialization function.

void audioamp_cfg_setup ( audioamp_cfg_t *cfg );

• Initialization function.

AUDIOAMP_RETVAL audioamp_init ( audioamp_t *ctx, audioamp_cfg_t *cfg );

• Click Default Configuration function.

void audioamp_default_cfg ( audioamp_t *ctx );

Example key functions :

• Set mux volume function

void audioamp_set_volume ( audioamp_t *ctx, uint8_t volume_value )

• Set channel volume function

void audioamp_set_volume_channel ( audioamp_t *ctx, uint8_t channel, uint8_t volume_value )

• Set normal opeation function

void audioamp_set_normal_operation ( audioamp_t *ctx )

Examples Description

AudioAmp Click is a stereo audio amplifier

The demo application is composed of two sections :

Application Init

Initialization driver enable's - I2C, turn on the Audio Amp click and start write log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    audioamp_cfg_t cfg;

    //  Logger initialization.

    log_cfg.level = LOG_LEVEL_DEBUG;
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    audioamp_cfg_setup( &cfg );
    AUDIOAMP_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    audioamp_init( &audioamp, &cfg );

    Delay_ms( 100 );

    log_printf( &logger, "~~~~~~~~~~~~~~~~~~~~~~\r\n " );
    log_printf( &logger, "    AudioAmp Click   \r\n " );
    log_printf( &logger, "~~~~~~~~~~~~~~~~~~~~~~\r\n" );

    log_printf( &logger, "       Power ON       \r\n" );
    
    audioamp_power_on( &audioamp );
    Delay_ms( 1000 );

    log_printf( &logger, "----------------------\r\n" );
}

  

Application Task

This is a example which demonstrates the use of AudioAmp Click board.

void application_task ( void )
{
    log_printf( &logger, " Set volume to lvl 15 \r\n" );
    log_printf( &logger, " for the next 10 sec. \r\n" );

    audioamp_set_volume( &audioamp, 15 );
    Delay_ms( 10000 );

    log_printf( &logger, "----------------------\r\n" );
    log_printf( &logger, " Set volume to lvl 5  \r\n" );
    log_printf( &logger, " for the next 15 sec. \r\n" );

    audioamp_set_volume( &audioamp, 5 );
    Delay_ms( 15000 );

    log_printf( &logger, "----------------------\r\n" );
    log_printf( &logger, " Set volume to lvl 10 \r\n" );
    log_printf( &logger, " for the next 20 sec. \r\n" );

    audioamp_set_volume( &audioamp, 10 );
    Delay_ms( 20000 );
    
    log_printf( &logger, "----------------------\r\n" );
    log_printf( &logger, "      Mute  mode      \r\n" );
    log_printf( &logger, " for the next 5 sec.  \r\n" );

    audioamp_mute_mode( &audioamp );
    Delay_ms( 5000 );
    
    log_printf( &logger, "----------------------\r\n" );
    log_printf( &logger, "     Unmute  mode     \r\n" );

    audioamp_unmute_mode( &audioamp );
    Delay_ms( 100 );

    log_printf( &logger, "----------------------\r\n" );
}

void main ( void )
{
    application_init( );

    for ( ; ; )
    {
        application_task( );
    }
}
